Abstract
The utility model discloses an aluminum alloy composite indoor cable having an optical fiber. The indoor cable is provided with an outer protecting layer, a metal band layer and an oxygen separating layer successively. The oxygen separating layer is provided with an optical fiber cable and a plurality of cores. Fillers are arranged between the optical fiber cable and the cores. The aluminum alloy composite indoor cable having the optical fiber in the utility model meets completely the requirements of electronic performance, communication capacity, mechanical performance, flame retardant property, fire safety performance and long service lifetime to the indoor cable of modern intelligent buildings. At the same time, the aluminum alloy composite indoor cable having the optical fiber in the utility model can substitute cooper electric cables, so as to save resource.
Description
Technical field
The utility model relates to and closes field of cables, particularly relates to a kind of aluminium alloy house lead in composite cable with optical fiber.
Background technology
Intelligent grid is as following electrical network, is the new industry that realizes safe and reliable, economical and efficient, environmental protection, positive pick up speed development both at home and abroad, and China's intelligent grid construction at present starts comprehensively.Fast development along with the intelligent grid construction; To being applied to the cable of intelligent grid; Again can transmission signals in electric energy transmitting; Not only will consider electrical property and security performance, also will consider factors such as environmental protection, energy-conservation, economy simultaneously, the composite cable of band optical fiber will become the developing direction of cable for building.
The utility model content
The purpose of the utility model is: to prior art, provide a kind of can satisfy modern building to the electric property of house lead in cable, communication performance, mechanical performance and under the fire condition requirement of fire resistance, security performance and the aluminium alloy house lead in composite cable of lower-cost band optical fiber.
For realizing above-mentioned purpose, the utility model adopts following technical scheme to realize:
The aluminium alloy house lead in composite cable of band optical fiber is disposed with outer jacket, strap layer and oxygen barrier layer, also is provided with optical cable and some core bodys in the described oxygen barrier layer, also is provided with filler between described optical cable and the core body.
Described core body is provided with insulator and the aluminium alloy conductor that is arranged in the insulator.
Described outer jacket, oxygen barrier layer, filler and insulating barrier, its material is low smoke halogen-free flame-retardant polyolefin.
Described aluminium alloy conductor, its material are the high ferroaluminium of rare earth.
Described metal tape is the Al-alloy metal band.
The beneficial effect of the utility model is: the utility model conductor adopt aluminium alloy wire press stranded, compare under the prerequisite that is satisfying serviceability with copper conductor and to greatly reduce cost; Physical crosslinking method (cross-linking radiation) is adopted in insulation; Utilize cable stranding space to add optical cable or optical fiber; Not only satisfy electric power transfer but also reach communicating requirement, simultaneously do not increase the outside diameter of cable again, do not reduce the security performance under electric, mechanical, the fire-retardant and fire condition of cable.The aluminium alloy house lead in composite cable of the band optical fiber of the utility model satisfies electric property, communication capacity, mechanical performance, fire resistance, fire safety evaluating performance and the long term life performance demands of modern intelligent building to the house lead in cable fully; Alternative again copper cable economizes on resources simultaneously.
